Hide (/ˈhaɪd/) is an English verb.

Hide is an irregular lexical verb; it has the third person form "hides" (/ˈhaɪdz/) , the -ing form "hiding" (/ˈhaɪdɪŋ(g)/) (with a dropped E), but an irregular preterite "hid" (/ˈhɪd/) and an irregular past participle "hidden" (/ˈhɪdən/). This pattern is the same as ride, rise and write. The preterite and past participle may be over-regularised to *"hided" (*/ˈhaɪdɪd/)
